Problems solved by technology

The disadvantage of this solution is: for a specific PUCCH format, the number of allocated PRBs must be fixed
However, PUCCH format 5 has a fixed bandwidth of one PRB, and thus does not support a varying number of PUCCHs

Abstract

The present disclosure relates to a wireless device and a network node and corresponding methods within a wireless communication system. The method for transmitting uplink control information UCI used in the wireless device includes: obtaining UCI including a plurality of UCI bits; mapping the UCI bits to a set of modulation symbols; obtaining a resource configuration, wherein the resource configuration Indicating at least one or more allocated resources available for transmission of the modulation symbols; mapping the modulation symbols to the resource configuration, wherein the resource configuration further indicates inclusion in the one or more allocated resources the allocated subcarriers in ; and transmitting the modulation symbols using the allocated subcarriers.

Description

technical field [0001] The present disclosure relates to wireless devices and network nodes for wireless communication systems. Furthermore, the present disclosure also relates to corresponding methods, computer programs and computer program products. Background technique [0002] In a wireless communication network, information is transmitted wirelessly between the different wireless devices of the system. For example, information may be transmitted downlink (DL) from a network node such as a base station (BS) to a user equipment (UE) or wireless device, or uplinked from a UE or wireless device to a network node or BS road (UL) transmission. The information can be both data and control information, and different channels can be used to transmit the information depending on whether the transmission is an uplink transmission or a downlink transmission, and depending on whether the information contains data or control information. In Radio Access Technology (RAT) Long Term ...
